15 Miss. Code R. § 16-1-45.2.19
A method of skin testing that is performed by injecting one-tenth (0.1) milliliter of purified protein derivative-tuberculin containing five (5) tuberculin units into the dermis (i.e., the second layer of skin) of the forearm with a needle and syringe. The area is examined between forty-eight (48) and seventy-two (72) hours after the injection. A reaction is measured according to the size of the induration. The classification of a reaction as positive or negative depends on the patient's medical history and various risk factors (see definition for "significant tuberculin skin test"). This test is used to evaluate the likelihood that a person is infected with M. tuberculosis. The Mantoux (TST) test should be administered only by persons certified in the intradermal technique.
